I am using Filbeat for log aggregation, which takes the logs to Kibana. Below is my error message that needs to be directed to Kibana:
2017-04-17 15:45:47,154 [JCO.ServerThread-8] ERROR com.webservice.AxisWebServiceClient - Client error
2017-04-17 15:45:47,154 [JCO.ServerThread-8] ERROR com.webservice.AxisWebServiceClient - The XML request is invalid. Fix the request and resend.

2017-04-04 12:47:09,362 [JCO.ServerThread-3] DEBUG com.Time - RFC_CALCULATE_TAXES_DOC,DEC[2],Total Time,39
i want only to have 2017-04-17 15:45:47,154 [JCO.ServerThread-8]ERROR and lines below the error to be send to Kibana, but i do get the INFO part as well
Below is filbeat.yml file
filebeat:

Request veterans help to select only the ERROR message pattern using regex.
In order to extract the error messages as a group, you'll need to modify your regex as following:
^\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2},\d{3}\s\[[A-Za-z0-9.-]*\]\sERROR (\w.+)
Explanation:
(\w.+)
This creates a group with all characters and the dot character, which captures the error message.

I have Elasticsearch, Filebeat and Kibana running on a Windows machine. Filebeat log has a proper log file and is listening to the path. When I look on the data in Kibana it looks fine.
My issue is that the message field is a String.
Example of one log line:
12:58:09.9608 Trace {"message":"No more Excel rows found","level":"Trace","logType":"User","timeStamp":"2020-08-14T12:58:09.9608349+02:00","fingerprint":"226fdd2-e56a-4af4-a7ff-724a1a0fea24","windowsIdentity":"mine","machineName":"NAME-PC","processName":"name","processVersion":"1.0.0.1","jobId":"957ef018-0a14-49d2-8c95-2754479bb8dd","robotName":"NAME-PC","machineId":6,"organizationUnitId":1,"fileName":"GetTransactionData"}
So what I would like to have now is that String converted to a JSON so that it is possible to search in Kibana for example for the level field.
I already had a look on Filebeat. There I tried to enable LogStash . But then the data does not come anymore to Elasticsearch. And also the log file is not genereated into the LogStash folder.
Then I downloaded LogStash via install guide, but unfortunately I got this message:
C:\Users\name\Desktop\logstash-7.8.1\bin>logstash.bat
Sending

Edit:
I tried to use Filebeat only. Here I set:
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~
- add_docker_metadata: ~
- add_kubernetes_metadata: ~
- dissect:
tokenizer: '"%{event_time} %{loglevel} %{json_message}"'
field: "message"
target_prefix: "dissect"
- decode_json_fields:
fields: ["json_message"]
but that gave me:
dissect_parsing_error
The tip with removing the "" at tokenizer helped. Then I got:
I simply refreshed the index and the message was gone. Nice.
But The question is now, how to filter for something in the new field?
The message says, your pipeline config is empty. It seems you did not configured any pipeline yet. Logstash can do the trick (JSON filter plugin), but Filebeat is sufficient here. If you don't want to introduce another Service, this is the better option.
It has the decode_json_fields option to transform specific fields containing JSON in your event to a . Here is the documentation.
For the future case, where your whole event is a JSON, there is the possibility of parsing in filebeat configuring the json.message_key and related json.* option.
EDIT - Added filebeat snippet as an processors example of dissecting the log line into three fields (event_time, loglevel, json_message). Afterwards the recently extracted field json_message, whose value is a JSON object encoded as a string, will be decoded into an JSON structure:
...
filebeat.inputs:
- type: log
paths:
- path to your logfile
processors:
- dissect:
tokenizer: '%{event_time} %{loglevel} %{json_message}'
field: "message"
target_prefix: "dissect"
- decode_json_fields:
fields: ["dissect.json_message"]
target: ""
- drop_fields:
fields: ["dissect.json_message"]
...
If you want to practice the filebeat processors, try to set the correct event timestamp, taken from the encoded json and written into #timestamp using the timestamp processor.
So I have a log line formatted as such:
2020-04-15 12:16:44,936 WARN c.e.d.c.p.p.BasePooledObjectFactory [main] Caution - XML schema validation has been disabled! Validation is only available when using XML.
I am using filebeat to send this directly to elasticsearch, which it does but the log.level is not set, the whole line becomes the message.
reading up on dissection I had intended to use:
processors:
- add_host_metadata: ~
- dissect:
tokenizer: "%{} %{} %{log.level} %{} [%{}] %{message}"
field: "message"
target_prefix: ""
which I expected to split into:
{
log.level: WARN
message: Caution - XML schema validation has been disabled! Validation is only available when using XML.
}
instead I get the same output as without the dissect:
{
message: 2020-04-15 12:16:44,936 WARN c.e.d.c.p.p.BasePooledObjectFactory [main] Caution - XML schema validation has been disabled! Validation is only available when using XML.
}
I'm just getting to grips with filebeat and I've tried looking through the documentation which made it look simple enough. however my dissect is currently not doing anything. host metadata is being added so I believe that the processors are being called.
How can I get the log level out of the log line? (preferably without changing the format of the log itself)
You need to pick another field name than message in the dissect tokenization since this is the name of the field that contains the original log message:
processors:
- add_host_metadata: ~
- dissect:
tokenizer: "%{} %{} %{log.level} %{} [%{}] %{msg}"
field: "message"
target_prefix: ""
I have been trying to set up elastalert monitoring on my ELK stack. For the beginning I want to set up a simple rule which will generate a notification if any disk on the file system has reached 80% usage. The rule seems to be working correctly but in the alert section I am not able to pass the data to python script. The uncommented command in the alert section gives following error
ERROR:root:Error while running alert command: Error formatting command: 'system.filesystem.mount_point' error.
Here is my rule file. Please excuse the formatting of the yaml.

Some observations:
On testing the rule file using the command python -m elastalert.test_rule rules/high_fs.yaml I get the output
Successfully loaded Metricbeat high FS percentage
Got 149161 hits from the last 1 day
Available terms in first hit:

system.filesystem.device_name
system.filesystem.used.bytes
system.filesystem.used.pct
system.filesystem.total

I should be able to access any of the fields mentioned above. When I run this rule using python -m elastalert.elastalert --verbose --rule rules/high_fs.yaml a list is printed on the screen
#timestamp: 2017-10-18T17:15:00Z
beat.name.keyword: my_server_name
num_hits: 98
num_matches: 5
system.filesystem.used.pct_max: 0.823400020599
I am able to access all the key value pairs in this list. Anything thats outside the list fails with the formatting error. Been stuck over this for long. Any help is appreciated.
UPDATE: A reply for the same problem on elastalert's github repo says that certain query types do not contain the full field data.
While I am not sure if this is the correct way to achieve what I was looking for but I was able to get the the desired output using the rule type any and writing my own filters. Here is how one of my rules file looks currently.
name: High CPU percentage
type: any
es_host: localhost
es_port: 9200

Hope it helps someone.

Actually what i am trying to do is, i am trying to use multiple logs specifying "document_type", if i remove "document_type" then it works, but why "document_type"(as i see this depcreated in filebeat 5.5) or "fields" is not working in it.
please help.
You have a syntax error in your config file.
The filebeat.prospectors keys wants an array value, but you are passing it a hash instead.
Plus, you have indentation problems.
This is a corrected version of your config file (without comments for brevity)

I would expect (based on the scares documentation) that this would split each line of test file into 2, example 'ggff', 'gg' would be message, 'ff' would be severity, but all i can see in my kibana is that 'ggff' is a message and severity is defaulted (?) to info. The problem is, i dont know where the problem is. Does it skip my pattern, does match in my pattern fail ? any help would be VERY appreciated.
Setting 'debug: true' in patterns.yml prints detailed info about matched patterns.
